Out of those 2 options Joomla would be your best bet because it has better support, more themes and plugins and is actively updated. If you just want a website for articles but no real customization then Drupal would be the better bet.
It totaly depends on what functionality you want to have. If you are interested in multimedia or more complex functionality then Joomla is a better option. Thus when it comes to build up a complex and robust website full of features and functionality, you should go with Drupal
Joomla is one of the best cms for every websites. Joomla is basically seo user friendly, but it can be used as a regular site which you can update without any knowledge of htm. You can create pages and posts, and with plugins, you can add a lot of functionality included standard in joomla.

Although I think with Drupal, additional security can also be achieved following simple tips and tricks like password should be chosen very carefully and must be changed frequently to cut down any chances of breach and etc.
